Design and Real-Time Implementation of an Embedded Anti-Jamming UAV Communication Architecture Using Adaptive Frequency Hopping, Intelligent Channel Switching, and Hybrid Optical Fiber Backup Control System

Overview

Unmanned Aerial Vehicles (UAVs) are widely used today in photography, surveying, inspection, and recreational activities, where maintaining a stable wireless connection is essential for safe and reliable operation. However, UAV communication systems are highly vulnerable to radio-frequency interference, especially in crowded wireless environments. Even brief signal disruptions can cause loss of control or mission failure. In this project, I designed and implemented a jam-resilient embedded communication system specifically for small UAV platforms. The system uses adaptive frequency hopping to automatically switch transmission channels when interference is detected, helping maintain a stable and reliable link. To evaluate the system’s performance, I conducted experimental testing and compared three scenarios: conventional fixed-frequency communication, frequency hopping operation, and a fiber-optic control setup used as a reference model. The experimental results showed a clear reduction in packet loss and improved communication stability when frequency hopping was applied under interference conditions. These findings demonstrate that implementing interference-resilient embedded communication strategies can significantly enhance UAV reliability and operational safety.
